Regulus is a bright (mag 1.3) blue-white star in the constellation of Leo. Lying close to the ecliptic (the plane of the Solar System) it's not uncommon for the Moon to pass in front of Regulus: this occurred last night at around 19.30. Unfortunately it was cloudy here until 20.25,when Regulus was just emerging from the Moon's north-eastern limb. At the same time, Venus was a brilliant object just above the western horizon. (Because of their distance from Earth, stars can, of course, only be seen as points of light: the apparent disc of Regulus is a photographic artefact)
